How recently, anonymous? If it was a couple of months ago, it’s likely that your espurr have grown old enough to leave their mother’s side, at which point it may be important to show your meowstic that you can be trusted with her kittens. Allowing her to care for the espurr during the day and starting them off with light training should help, as you’re actively showing your meowstic that you have no intention of overstepping your bounds while at the same time allowing her to see how you intend on treating her kittens when they’re old enough to battle.
If, however, they’re younger than eight weeks old, then this is indeed a problem and may indicate that they’ve imprinted on you. Granted, this isn’t entirely a bad thing; it’s simply that it’s understandable that your meowstic feels some level of jealousy or apprehension if this is the case. As separating yourself from the kittens may cause them stress (never mind the fact that espurr generally develop telekinetic abilities at a young age and may find ways of getting back at your side regardless of what you do), it may be a good idea to move their bed into your bedroom and allow the family to sleep with you until the kittens grow more independent.
Alternatively, it may be possible to coax your espurr into their bed (as opposed to yours) by covering it with a shirt you’ve worn or leaving an object that smells like you with your meowstic. If your espurr can curl up with something that reminds them of you in their bed, then they’ll be less likely to seek you out during the night.
Best of luck, anonymous, and congratulations on the new additions to your family!
